Nambala yachibadwa yolembera katundu ndi zigawenga
Ma barcode ndi ma QR codes omwe amagwiritsidwa ntchito polemba chilichonse kuyambira ma T-shirts m'masitolo ogulitsa zovala mpaka mainjini agalimoto posachedwapa angalowe m'malo ndi makina a DNA osawoneka ndi maso omwe sangathe kuchotsedwa kapena kunamiziridwa.
Munkhani yomwe idasindikizidwa mu Nature Communications, asayansi aku University of Washington ndi Microsoft adapereka dongosolo lolembera ma molekyuluimatchedwa nungu. Malinga ndi ofufuza. Zidzakhala zovuta kuti zigawenga zizindikire ndikuchotsa kapena kusintha DNA tag zinthu zamtengo wapatali kapena zosatetezeka monga mapepala ovota, zojambulajambula kapena zolemba zamagulu.
Kuphatikiza apo, amati yankho lawo, mosiyana ndi zolembera zina zambiri, ndizokwera mtengo. "Kugwiritsa ntchito DNA kulemba zinthu kwakhala kovuta m'mbuyomu chifukwa kulemba ndi kuwerenga nthawi zambiri kumakhala kodula kwambiri komanso kumatenga nthawi, ndipo kumafuna zida za labotale zodula," wolemba wamkulu wa kafukufukuyu pa yunivesite ya Washington wophunzira womaliza maphunziro adauza AFP. Katy Doroshchak.
Porcupine imakulolani kuti mupange zidutswa za DNA pasadakhalekuti ogwiritsa ntchito ali ndi ufulu kupanga ma tag atsopano. Dongosolo lolemba zilembo za Porcupine lidakhazikitsidwa pakugwiritsa ntchito zida za DNA zomwe zimatchedwa molecular bits, kapena "molbits" mwachidule, malinga ndi zomwe atolankhani aku University of Washington adatulutsa.
"Kuti tiyike chizindikiritso, timaphatikiza pang'ono pa digito ndi molbit," akutero Doroschak. "Ngati digito ya digito ndi 1, timayiwonjezera pa tag, ndipo ngati ili 0, timayinyalanyaza. Izi zimatsatiridwa ndi kuyanika kwa zingwe za DNA mpaka zitakonzeka kusinthidwa. Zinthu zikalembedwa, zimatha kutumizidwa kapena kusungidwa. ” Pamene wina akufuna kuwerenga chizindikiro, moisturizing ndi kuwerenga ndi nanoporous sequencer, wowerenga DNA ndi wocheperako kuposa iPhone.
Mosiyana ndi machitidwe omwe alipo kale, kuwonjezera pa chitetezo, njira yochokera ku DNA imathanso kuyika zinthu zomwe zingakhale zovuta kuziyika.
“Sizingatheke kulemba thonje kapena nsalu zina ndi njira zodziwika bwino monga Ma tag a RFID ndipo, koma mutha kugwiritsa ntchito chizindikiritso chochokera ku DNA chowerengeka ndi chifunga, "Doroshchak amakhulupirira. "Izi zitha kugwiritsidwa ntchito pamakina ogulitsa komwe kutsata ndikofunikira kuti tisunge mtengo wazinthu."
Kulemba kwa DNA ili si lingaliro latsopano, koma mpaka pano ladziwika makamaka kuchokera ku ntchito ya apolisi yolimbana ndi zigawenga. Pali mankhwala ngati Sankhani DNA Chizindikiro chopopera, amagwiritsidwa ntchito kuletsa ndi kuletsa kuukira anthu ndi zigawenga zina. Izi ndizothandiza pamilandu yochitidwa ndi achifwamba pama mopeds ndi njinga zamoto. Aerosol imayika magalimoto, zovala ndi khungu la madalaivala onse ndi okwera omwe ali ndi ma DNA apadera koma osawoneka omwe amapereka umboni wazamalamulo wolumikizana ndi olakwawo.
Njira ina yomwe imadziwika kuti DNA Guardian, imagwiritsa ntchito zosavulaza thanzi, zolembedwa mwapadera, zozindikirika UV kuwala banga lomwe limakhala pakhungu ndi zovala kwa milungu ingapo. Ulamulirowu ndi wofanana ndi utsi wa SelectaDNA.
